usort function in a class

Question

I have a function which sorts data in a multidimensional array, as shown below:

 \"James\");  
         


        

Answer 1

order_new is a class method not a global function. As the PHP-Manual suggest you can use in this case

usort($data, array($this, "order_new")); 

or declare order_new static and use

usort($data, array("myClass", "order_new"));
